      include: Clean up includes · 90ce6e26
      由 Peter Maydell 提交于 
      Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This commit was created with scripts/clean-includes.

NB: If this commit breaks compilation for your out-of-tree
patchseries or fork, then you need to make sure you add
#include "qemu/osdep.h" to any new .c files that you have.

      util - add automated ID generation utility · a0f19136
      由 Jeff Cody 提交于 
      Multiple sub-systems in QEMU may find it useful to generate IDs
for objects that a user may reference via QMP or HMP.  This patch
presents a standardized way to do it, so that automatic ID generation
follows the same rules.

This patch enforces the following rules when generating an ID:

1.) Guarantee no collisions with a user-specified ID
2.) Identify the sub-system the ID belongs to
3.) Guarantee of uniqueness
4.) Spoiling predictability, to avoid creating an assumption
    of object ordering and parsing (i.e., we don't want users to think
    they can guess the next ID based on prior behavior).

The scheme for this is as follows (no spaces):

                # subsys D RR
Reserved char --|    |   | |
Subsystem String ----|   | |
Unique number (64-bit) --| |
Two-digit random number ---|

For example, a generated node-name for the block sub-system may look
like this:

    #block076

The caller of id_generate() is responsible for freeing the generated
node name string with g_free().

      Stop including qemu-common.h in memory.h · fba0a593
      由 Peter Maydell 提交于 
      Including qemu-common.h from other header files is generally a bad
idea, because it means it's very easy to end up with a circular
dependency. For instance, if we wanted to include memory.h from
qom/cpu.h we'd end up with this loop:
 memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h

Remove the include from memory.h. This requires us to fix up a few
other files which were inadvertently getting declarations indirectly
through memory.h.

The biggest change is splitting the fprintf_function typedef out
into its own header so other headers can get at it without having
to include qemu-common.h.

      pidfile: stop making pidfile error a special case · fee78fd6
      由 Michael Tokarev 提交于 
      In case of -daemonize, we write non-zero to the daemon
pipe only if pidfile creation failed, so the parent will
report error about pidfile problem.  There's no need to
make special case for this, since all other errors are
reported by the child just fine.  Let the parent report
error and simplify logic in os_daemonize().

This way, we don't need os_pidfile_error() function, since
it only prints error now, so put the error reporting printf
into the only place where qemu_create_pidfile() is called,
in vl.c.

While at it, fix wrong indentation in os_daemonize().

      util: Emancipate id_wellformed() from QemuOpts · f5bebbbb
      由 Markus Armbruster 提交于 
      IDs have long spread beyond QemuOpts: not everything with an ID
necessarily goes through QemuOpts.  Commit 9aebf3b8 is about such a
case: block layer names are meant to be well-formed IDs, but some of
them don't go through QemuOpts, and thus weren't checked.  The commit
fixed that the straightforward way: rename the internal QemuOpts
helper id_wellformed() to qemu_opts_id_wellformed() and give it
external linkage.

Instead of using it directly in block.c, the commit adds wrapper
bdrv_is_valid_name(), probably to hide the connection to QemuOpts.

Go one logical step further: emancipate IDs from QemuOpts.  Rename the
function back to id_wellformed(), and put it in another file.  While
there, clean up its value to bool.  Peel off the bdrv_is_valid_name()
wrapper.

[Replaced stray return 0 with return false to match bool returns used
elsewhere in id_wellformed().

      dma-helpers: Fix too long qiov · 58f423fb
      由 Kevin Wolf 提交于 
      If the size of the scatter/gather list isn't a multiple of 512, the
number of sectors for the block layer request is rounded down, resulting
in a qiov that doesn't match the request length. Truncate the qiov to the
new length of the request.

This fixes the IDE qtest case /x86_64/ide/bmdma/short_prdt.
